yea - you are absolutely right. I guess thats why so many patent anchors do exist and not just "the one". Also - this makes it hard to make a decision if you want to purchase one.

In blue water it's very easy to check if the anchor sits well and how the ground looks like, since you can look into the water like 15m.

In the baltic sea it's more a gamble because you can see like 15..30cm into the water. So usually you see how the ground looks like, when you pull the anchor up. Definitely never try to anchor if "stone" is written in the sea chart. Due to to the zero visibility it's hard to dive to the anchor if it gets stuck somewhere.
